Abstract:: [Objective]The aims of this study are to evaluate the spatiotemporal trends of soil erosion, to reveal the contributions of driving factors, to elucidate the impacts of ecological restoration policies, and to provide a scientific basis for the management of soil erosion on the Tibetan Plateau. [Methods]This study assessed the temporal and spatial characteristics of soil erosion by water on the Tibetan Plateau from 1990 to 2020, and identified the contribution of climatic, anthropogenic and topographic factors to soil erosion by Random Forest Regression. [Results](1)The average soil erosion rate on the Tibetan Plateau was 305.78 t/km², and more than 80% of the area was slightly erosion during 1990—2020. Soil erosion decreased before 2010 and increased after 2010, showing a nonlinear variation.(2)Climate factors had a greater impact on soil erosion than anthropogenic factors in the Tibetan Plateau, and annual precipitation was the main factor on soil erosion. In addition, since 2010, the influence of anthropogenic factors on soil erosion gradually increased. [Conclusion]Climate factors are the primary driving force inducing soil erosion in the Tibetan Plateau. The ecological restoration policies implemented in the Tibetan Plateau have initially achieved results, but the impact of climate change on soil erosion is more significant. Additionally, Random Forest Regression is effective for exploring the driving factors on soil erosion.
